Jamstix Drum Map Problem

Hello friends at the Cakewalk forum,
 
I created a new drum map using the pass thru map in the drum map manager to use with Jamstix.  When I play a note on the keyboard, I get an endless loop of noise.  If I use no drum map or start with a blank drum map, it works fine.  I also tried the pass thru map with NI Battery and that works fine. Does anyone know what is causing this?  Thanks
